'Ihere'is he pivotal bearings whereby the vessel is pivotally connected to the supporting framework consist of the cheek plate 0 and trunnion plate f shown in detail in Fi s. .6, 7 and 8. Said cheek plate consistsv o. a chambered plate secured to the upright (Z and having a vertically arranged notch e vessel is in posit on in its bearing, it concross braces and yet at:

Said head is adapted said trunnion and the top of the chan'ibcred port-ion of plate 7',

lindrically recessed at the inner surface of is tilted downward at one end the-contents rush toward that end, the over balanced weight of the vessel and contents tending to stretch the springs g which consequentl assist in the return movement of the vessei: as in the known types of machine. In this machine however, the relative dimensions are such that the water and clothing which are at the bottom of the vessel when moving in one direction will be deflected by the breakers o' the end (4 and breakers c in such manner as to cause a complete overturning with the result that the portion which was on the bottom at first, will next occupy a position on the top. T he air seems to be, by the action of the water, compressed at the ends of the vessel under the breakers c and perhaps behind the breakers c and c, with the result that a complete overturning of the contents is effected at every movement of the vessel. After the contents are deflected by brcakcrs c until they dash down upon the remaining portion of the contents, and as the two portherein for receiving the trunnion f of plate Said notch, being open at the top, permits the entire vessel being removed from the supporting frame by merely lifting it out of engagement with plate 6. Said plate 7' is fastened to the vesselside a and has formed thereon the trunnion f with the head 7' which is formed at the extremity of l is adapted to enter the chamber of the cheek plate in such manner as to engage the'same and prevent play of the parts in a direction parallel to the axis of oscillation. Inasmuch as the vessel itself is rigid and the trunnion plate 7' is rigidly secured thereto and the plates 0, f, are mutually interfitting', it follows that when the stitutcs'a tie piece and brace which prevents the spreading of the uprightd, and prevents disengagement of the parts. One important l advantage in this construction is that itl permits the supporting frame to be made ight and substantially without interfering l 'ords a construction which is rigid and durable. By preference tions are thus moving in opposite directions the plate extends to the bottom of the l a very forceful agitation and intermixing takes place, the action being in the nature of ablow of the downward moving jet upon 1 the remainder of the contents. As a result 1 of this action water and air are forced through the meshes of the fabric thereby dislodging and removing all dirt and grease. Moreover as a result of the proportions and construction of the parts, the contents on their return drop beyond the center of the vessel and thus assist in the reversal of movement of the vessel This reduces to a minimum the amount of labor required to operate the machine.

' The size and shape and proportions of the several parts are what have appeared to me to be the best, but they may of course, be

varied.

It is important that the tub at its ends be pivoted far below its center of gravity and considerably below the surface of the normal quantity of water which is to be used in the tub. It is this method of mounting which tends to throw the water bodily from one sidb of the tub to the other as the oscillations proceed as distinguished from simply throwing the water to and fro within the tub which is the action when the tub is rocked on rockers or is pivoted above its center of gravity or above the normal level of water within the tub.

That I claim as new and desire to secure by Letters Patent, is;

1. In a washing machine the combination of a supporting frame, a vessel pivotally supported thereon, a spring connected at one end to said vessel for assisting in oscillating the same about its axis, and connections between said spring and said frame,

machine where it has an eye for attachmentto tension spring-g. There is one of these tension springs upon each side of the machine, and they extend downward therefrom and are connected at their lower extremity to the yoke 72 -Said yoke is aperl tured to receive the yoke rod 2' and in the preferred construction the'upper portion of said rod is threaded and has a wing nut 2' thereon adapted to engage the yoke h and adjustablyretain the same in position upon said rod. At the lower end of said rod there is formed a .head i as best shown in Figs' 9, l0 and 11; This head is, in the preferred form, cylindrical or approximately so with its axis transverse to the length of the rod. to be engaged by the plate j which is rigidly secured to the cross piece d of the framework and is chambered to receive said head. There is a slot' in said slot being of a length greater than the length of said head, and of a width than the length of said head. By this construction the head may be slipped into the slot in plate but by turning it around 90 may be retained within said plate. By preference, in order that the rod may tend to remain in its operative position, plate j is cy thetop at point j as shown in Figs. 10 and 11. This forms a hearing about which as a center the rod may rock when the vessel is oscillated.

In operation, the vessel is tilled perhaps a third or quarter full of water and clothing or fabrics, and after the cover Z) is closed the vessel is caused by hand to oscillate upon the trunnion bearings e, f. ;\s the machine they continue on.

crosswise of the pl plate secured to said-frame and having an I aperture therein, said connections also 1ncludthe length of the plate aperture so that the head may enter, but the length of said head being greater than the width of said plateaperture so that the pin may not be withdrawn when the head is turned ate aperture.

machine the combination 1 pivotally springs connected at one to said vessel, a yo e connected "tothe d springs, a rod adjustably connected to said yoke, and a chambered plate fastened to said frame, said plate having a slot therein, and said rod having a cylindrical head thereon adapted to rock against the inner surface of said plate, said head being shorter than the length and In a washing bottom of the tub longer than the width of the slot in said plate.

3. I11 a washing machine,'the combination of a tub with laterally projecting trunnions on its ends below the center of gravity of the tub and below the normal level of water within the tub and considerably above the supports on Which the trunnions'are pivoted, lates connected with such trunnions secure to the ends of the tub and extending downward to the bottom a swivel plate on the frame beneath the tub and springs which are attached to a swivel attachment on the frame at one end and at the other end to such plates. In witness whereof, I have hereunto subscribed my name in the presence of two wit- DGSSBS.
